BACKGROUND Chromosome 9p21 single nucleotide polymorphisms (SNPs) have been shown to be associated with coronary heart disease in multiple studies. The aim of the present study was to identify whether these SNPs are associated with recurrent myocardial infarction (MI), revascularization, or death in acute coronary syndrome (ACS) patients or in those undergoing coronary artery bypass grafting (C...
PURPOSE To define more clearly the role of the tumor suppressor gene p16 in uveal melanoma by determining the relative contribution of all known mechanisms of p16 inactivation in this tumor. METHODS A comprehensive genetic analysis of the p16 gene was performed in 33 primary sporadic ciliochoroidal and choroidal melanomas. Fourteen highly polymorphic microsatellite markers surrounding the p16...
OBJECTIVE We tested the hypothesis that expression of transcripts adjacent to the chromosome 9p21 (Chr9p21) locus of coronary artery disease was affected by the genotype at this locus and associated with atherosclerosis risk. METHODS AND RESULTS We replicated the locus for coronary artery disease (P=0.007; OR=1.28) and other manifestations of atherosclerosis such as carotid plaque (P=0.003; O...
Study Hypothesis A novel locus on chromosome 9p21 has been identified in numerous genome-wide association studies as the most highly associated with coronary artery disease (CAD) and myocardial infarction. Understanding the mechanism by which the locus influences disease has been a challenge because the locus lies entirely within noncoding DNA—in a so-called “gene desert” at a long distance fro...
BACKGROUND AND PURPOSE Sequence variants on chromosome 9p21.3 are implicated in coronary artery disease and myocardial infarction, but studies in ischemic stroke have produced inconsistent results. We investigated whether these conflicting findings were due to false-positive studies confounded by population stratification or false-negative studies that failed to account for effects specific to ...
Chromosome position 9p21 encodes three-tumor suppressors p16(INK4a), p14(ARF), and p15(INK4b) and the long non-coding RNA ANRIL (antisense non-coding RNA in the INK4 locus). The rs11515 single-nucleotide polymorphism in the p16 (INK4a) /p14 (ARF) 3'-untranslated region is associated with glioblastoma, melanoma, and other cancers. This study investigated the frequency and effect of rs11515 genot...
The chromosome 9p21 region has been implicated in the pathogenesis of multiple cancers. We analyzed 9p21 single nucleotide polymorphisms (SNPs) from eight genome-wide association studies (GWAS) with data deposited in dbGaP, including studies of esophageal squamous cell carcinoma (ESCC), gastric cancer (GC), pancreatic cancer, renal cell carcinoma (RCC), lung cancer (LC), breast cancer (BrC), bl...
We have performed representational difference analysis (RDA) on DNA from tumor cells and normal fibroblasts isolated from the ascites of a patient with ovarian cancer. Five of six products of the RDA were homozygously deleted from the tumor DNA. One of these products has been characterized and identifies a homozygous deletion of approximately 6.9 Mb at chromosome 9p21 in the original ovarian tu...
